  • Using ship tracks to characterize the effects of haze on cloud properties

    Creator:
    Segrin, Matthew S.
    Abstract:
    1-km MODIS observations of ship tracks off the west coast of the U.S. are used to characterize changes in cloud visible optical depths, cloud droplet radii, cloud cover fraction, and column cloud liquid water amount as low-level marine clouds respond to particle pollution from underlying ships. This study re-examines the...

  • Properties of marine stratus and stratocumulus derived using collocated MODIS and CALIPSO observations

    Creator:
    Hayes, Christopher R.
    Abstract:
    Adiabatic parcel models suggest specific relationships between cloud thickness and cloud properties. Such relationships govern cloud radiative forcing and thus cloud feedbacks in the climate system. Current remote sensing techniques work well at measuring these properties in low-level cloud systems that are overcast. Significant biases exist, however, when measuring cloud...

  • Overestimation of cloud cover in the MODIS cloud product

    Creator:
    Schuetz, Andrea M.
    Abstract:
    The operational processing of MODIS imagery to produce the MOD06 cloud product is based on the assumption that cloudy 1-km pixels are overcast. This assumption is examined using a partly cloudy pixel retrieval scheme, which allows for fractional cloud cover within the 1-km pixels. Cloud flags attached to 250-m MODIS...
